HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 392,715, dated November 13, 1899.

Application filed October-28, 1887. Serial No. 253,606. (No model.)

To all whom it may concern:

Be it known that I, .Linus H. BUsnLL, of Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Heel-Burnishing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a machine for burnishing boot and shoe heels, is an improvement upon the invention described in another ap plication of mine filed April 16, 1887, Serial N o. 235,022, and consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the drawings and to the claims to bc hereinafter given, and in `which my invention will be particularly pointed ont.

Figure .1 of the drawings is a front elevation of a machine` embodying my invention with the jack in position for burnishing the central portion of the heel-edge. Fig. 2 is a side elevation of the same with the jack in position for placing the boot or shoe thereon or removing it therefrom. Fig. 3 is an elevation of the head of the machine removed from the supporting-column. Fig. 4.- is a plan of the same. Fig. 5 is a plan of the su pporting-column with the head removed and the jack in position for removing the shoe therefrom. Fig. 6 is aplan of a portion of the jack-lever and the adjustable last-supporting pin. Fig. 7 is an end elevation of the same. Fig. 8 is a section on line m :c on Fig. 6, but showing the last-supporting pin in elevation.

In the drawings, Ais the column, supported by the legs A. B is the driving-shaft, carryL ing the pulleys C, C, and C2. I) is the frame ofthe head of the machine; E, the crank-shaft for operating the reciprocating burnishing` tool, and carrying the pulley F and hand Wheel G; H, the verticallyreciprocating toolcarrier. J is the belt for transmitting motion from the driving-shaft B to the shaft E. K is a bracket bolted to the side of the frame D, and having mounted in bearings therein the shaft L, carrying at one end the pulley L and at its other end a heel-seat-burnishing tool, M, to which rotary motion isimparted by the belt N, leading from the pulley L to the pulley N on the driVingShaftB; and Ois the jaek-rod5 O', the jack-lever; P, the jack-supporting stand; Q, the jack-controlling spring, and R the spring adjusting and supporting bent rod, all constructed, arranged, and operating substantially as shown and described in saidprior application herein referred to.

I will now proceed to describe theimproven ments which constitute my present invention, and forAwhich I desire to obtain Letters Patent.

In the operation of the machine described in my said prior application I havefound it somewhat inconvenient to hold the jack-rod away from the burnishing-tool against the tension of its spring while removing a shoe from the jack and placing another thereon. To obviate this difficulty I clamp upon the jack-rod O the hook OIl and iirmly secure to the base of the column A an arm, O3, with the upper end of which the hook Ol engages when the jack is swung to the left and rear of Fig. l, as shown in Figs. 2 and 5, in which position the jack will be firmly held by the tension of the spring It, so that the operator has both hands free for use in applying the shoe to or removing it from the jack. This is a very great advantage. I have also found that the holes in the tops of the heel portions of the lasts are not always bored at the same distance from the rear end of the last, and also that the heels of boots and shoes do not always bear the same relation to the rear of the boot or shoe. Itis, however, very desirable that the boot or shoe should be so jacked that it shall rotate about an axis corresponding as nearly as possible to the center of the heel in all eases. In order to attain this very desirable end, I secure to theinner end of the jack-lever O,` by means of the pivot-screw a, the arm b, provided with the longitudinal dovetailed groove c, in which is fitted so as to be movable endwise therein the block d, which may be clamped in any desired position in said groove by the last-supporting pin S, the main body of which is made manysided and tapering, and provided with the collar e, to bear upon the face of the arm b upon each side of the groove c, and with the serew-shankj", to screwinto a correspondinglythreaded hole in the block or nut d, all as shown in Figs. 6, 7, and 8.

By making the main body of the pin S po lygonal in cross-section and tapering, it is adapted to t'holes of different sizes in the lasts, and the last is effectually prevented from revolving about said pin; but the last and shoe thereon, together with the pin S and the arm b, are made to revolve about the axis of the pivot-screw a, and it Will therefore be readily seen that by so adjusting the block (Z and the pin S that the axis of the pin S shall bear the same relation to the axis of the pivot-screw t that the hole in the last does to the center of the heel the vibrations ol the jack due to rotating the shoe-heel while in contact with the bnrnishing-tool will be reduced to a minimum.

Vhat I claim as new, and desire to secure by Letters Patent of the 'United States, is

1. In a bnrnishing-maehine having a universally-movable jack-rod and a spring for moving the free end of said jack-rod toward the burnishing-tool, a hook fixed upon said jack-rod, in combination with a fixed arm or stop to engage said hook when said jack-redis moved into a certain predetermined position and hold said jack in said position.

2. The combination,with thejack-rod O and the jack-lever O', of the arm b, pivoted to said lever and provided with a dovetailed slot or groove extending longitudinally thereof, the block or nut d, fitted to said dovetailed groove, and a last-supporting pin screwed into said block and adapted to clamp it in any desired position in said groove.

3. In a boot or shoe supporting jack, the combination of a pivoted arnn and a pin to enter the hole in the shoe-supporting last,ad just-ably secured in said pivoted arm, with its axis parallel to the pivotal axis of said arm, and having its main body made polygonal in cross-section and tapering toward its free end.

In testimony whereof I have signedv my name to this specieation,in the presence oftwo subscribing witnesses, on this 22d day of October, A. l). 1887.

JAMES I-I. BUSELL.
